CBS – Saying public confidence in the Police Department “has been shaken and eroded” in the wake of the Laquan McDonald controversy, Mayor Rahm Emanuel announced Tuesday that Police Supt. Garry McCarthy is out as the city’s top cop.

The mayor said he and McCarthy began discussing the future of the department on Sunday, and on Tuesday morning, he asked for the superintendent’s resignation. First Deputy Supt. John Escalante will serve as acting superintendent while the Chicago Police Board conducts a national search for a permanent replacement for McCarthy.
